I found a couple EVGA Geforce GTX 560TI's at my local Fry's for $240 each. | |

The GTX560 Ti and GTX550 Ti are fairly average cards for crunching at GPUGrid. | |

Wow good info! Do you think the performance difference is a software issue or a hardware one? Meaning do you think they could fix it with some patch to the drivers or is this something that at a hardware level they just didn't do a good job? | |

It's fundamentally a hardware issue and so far there has been no software work around. I don't expect this to change. | |

It's more of a "hardware design choice, which doesn't work very well with our code" than a "hardware issue". Those 48 Shader blocks are not much more expensive than the 32 shader blocks and they do work with some code. It's just that the current GPU-Grid app does not beling into this group. And I wouldn't hold my breath for any changes here - the team is pretty busy doing other stuff already. | |

All of you are right, but imho if you plan to crunch for Gpugrid 24/7, then GTX 470/480/570 aren't a wise choice: heat/consumption are 2 great issues you should consider very well. | |

Your GTX 560 Ti is a good GPU, but it is not especially good when it comes to GPUGrid crunching; a GTX 470 can do twice as much work. Yes it uses more electric (TDP is 215W) but a GTX 560 Ti has a TDP of 170W. So all things considered a GTX470 does more work per Watt. | |

Agreed - high power consumption doesn't automatically mean inefficient. The opposite is true here, as SK points out. Of course you have to handle (and pay for) the power consumption. But taking your argument to the extreme one could say that your GTX560Ti is not very good either, as heat/power consumption are too high. A smaller 40 W card with 1/10th the performance of yours can be handled much easier ;) | |

My will was to buy a pretty fast gpu card to crunch for this project, BUT with a "decent" price/heat/consumption. I wasn't looking for the better point per watt ratio. I think 560 Ti is a good compromise. At least, I hope so :) | |

It's certainly not a bad card. SKs point was just that for "only" 45 W more (26%) and similar price you could have gotten the GTX470, which would do ~100% more work at GPU-Grid. | |

Yes it uses more electric (TDP is 215W) but a GTX 560 Ti has a TDP of 170W. So all things considered a GTX470 does more work per Watt. I doubt that. When an application (like GPUGrid) utilizes only 2/3 of the shaders, the GTX560Ti won't consume it's peak TDP (however it will be slightly over the 2/3 of the max TDP). I think the GTX560Ti does more work per Watt than a GTX470, while it won't do more work than a GTX470. | |

In the pioneer times (did we leave them yet?) ne GPU drew anywhere near it's TDP at GPU-Grid. Better hardware utilization can have changed this in recent times, however. And the relation "typical power draw" / "GPU-Grid power draw" should be similar for different cards using the same architecture. | |

The fact that a GTX560 Ti (and other CC2.1 cards) can’t use all their shaders here is the negative aspect of the card. While there may be a tiny power saving from not using 1/3 of the shaders, this does not do much to offset the loss of performance. | |

It's fundamentally a hardware issue and so far there has been no software work around. I don't expect this to change. It's a software issue. The GPUGrid app does not properly utilize the architecture of the CC 2.1 cards. Wouldn't think that it would be difficult to fix... | |

For me, the GTX 560 Ti is so close the the power limit my computer room can stand that the GTX 470 is out of the question, even if it does more work for each watt. | |
